Generally
to determine the size needed for a
Dome mirror, we would use the rule-of thumb that 1 inch
= 1 foot you are standing away from the mirror as the
maximum distance the mirror is effective.
How do I choose the right mirror for my needs? Generally you need to consider three issues: visibility, how far the mirror is from you, and the viewing angle or area you want to see. Round and "roundtangular" mirrors allow a 160-degree view. They also provide the best view. The 1/4 dome mirror provides a 90-degree view and works well in corners. The 1/2 and full dome mirrors provide the widest viewing area of 180 degrees. If you do not need the wide-angle view, you should try using a round or "roundtangular" mirror because objects look smaller in the dome mirrors than in these. If you do need the wide angle and a detailed view, go to a larger sized dome. A good starting point is 20 feet for an 18" round mirror and 10 feet for the same size dome. What is a good mirror for the office? For inside the office or home, a quarter-, half-, or full-dome mirror is a good choice. In hallways, for example, a quarter-dome mirror can allow people walking into a blind corner to see around it and avoid mishaps. For surveillance purposes, a full-dome can offer panoramic views of wide areas. The smaller (12"x18") "roundtangular" can also be used in an office or store. The larger round mirrors (26" and 30") are commonly used in convenience stores where they can be placed across the room and still provide a good (detailed) view of persons in the store. Which Mirror is good for outside? For outside uses--such as, in driveways, alleys, parking garage entrances and exits--a round convex mirror works very well. The "roundtangular" mirror will allow you to avoid the sun more than the round mirror, and some customers feel it has a more attractive design. Both mirrors work equally well at viewing left to right angles. How do I decide what kind of backing I need for my mirror? For the inside, any of the backing will last a very long time. For the ultimate in durability and longevity we recommend using a steel backing for outside. The steel-backed mirror is strong and the lens is sealed allowing the mirror to stand up to all but the worst of weather conditions. These mirrors are being used in many outdoor applications including ocean-going vessels. The hardback mirror is also weather resistant and UV resistant. For mild weather conditions or where the mirror is somewhat protected from high winds, the hardback mirror will do the job. The painted backing will withstand rain and some wind. The molded rubber seal is UV resistant and does not melt or sag on hot summer days. Where there is constant moisture and constant freezing and thawing (even without wind), you should consider the steel backed mirror for longevity. For inside the office, home, garage, factory or any area protected form the rain or high winds, the hard backed mirror will last a very long time. What are the mirrors themselves made of? Glass or mirror-grade virgin acrylic with a silver coating on the back side. The Silver coating is coated three times with an epoxy paint. How do I decide whether to use an acrylic or glass mirror? For rough conditions where the mirror could be broken, you will want to use an acrylic mirror, as they are virtually indestructible. If there is little chance of the mirror being hit or subjected to rough treatment and you do NOT have a safety issue, then a glass mirror will more than meet your needs. The glass mirrors are more resistant to scratches and normal glass cleaner can be used. There is very little if any difference in the reflective qualities of glass compared to acrylic. (You may get an argument out of someone if you quote me on that one!) The Acrylic mirrors are difficult to break and there is much less danger of being cut from broken acrylic than from broken glass. On the negative side, you should be careful to only clean the acrylic with a mild soap and a clean cotton cloth. You can also use products on the market made specifically for cleaning acrylic. Note: (Lemon Pledge works great!) Outside, the acrylic seems to resist water spots better that the glass so acrylic doesn't have to cleaned as often. How do I mount my mirror? Most mirrors come with standard wall
mounts, which includes a mounting bracket and a ball
swivel. The bracket can be installed on a wall, tree,
or most fixed objects with bolts or large screws. (See
installation for a picture of the bracket) Note:
Before the ball swivel can be repositioned you must
loosen the three screws around the ball. After you
have positioned the mirror, tighten the screws to lock
the ball from moving. Are there alternate ways of mounting mirrors? Yes. For special locations you can consider mounting mirrors on a pole purchase d separately--such as a fence post, etc. You can also use a galvanized pipe, which is available at Home Depot, to make a post by digging a 2 ½ foot hole filled with concrete and topped with an end cap. Note: The 4"x4" wooden post is the method I recommend for most applications.. How do I clean my mirror? Acrylic mirrors should be cleaned with a soft cloth and very mild soap. We suggest using Lemon pledge. For the Glass mirrors, any glass cleaner may be used. (DO NOT USE GLASS GLEANER ON ACRYLIC MIRRORS.) Why can't I order extra-large mirrors through the web store? Extra-large mirrors require larger boxes than can be shipped via UPS. They require a special shipping formula and must be calculated on a case-by-case basis.
